Anion-exchange membranes are useful for electro-membrane processes such as electrodialysis (water desalination, separation of inorganics from organic molecules, separation of specific inorganic ion, etc.), in-situ ion-exchange and ion substitution, electro-deionization for producing ultrapure water, polymer electrolyte membrane for alkaline fuel cell and electrolysis applications. The present invention discloses an acid and base resistant fluorinated hydrocarbon based anion-exchange membrane and its method of preparation thereof. In the first step co-polymerization is carried out between N-isopropylacrylamide and 1-vinylimidazole. In the second step, obtained inter-polymer of isopropylacrylamide-co-vinylimidazole co-polymer is mixed with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) (IA-co-VI/PVDF-co-HFP), which is used for casting membrane film of desired thickness. The obtained casted membrane thin film is quaternized in methyl iodide solution.
